CEMENT BUILDING.

- Specification of Letters latent.

Patented Aer-.26, 1921.

Application filed December 23, 1919. Serial No. 346,858.

To all whom it may concern Be it knownthatI,NIQHOLAsFRISQHMANN, acitizen ofthe United States, and resident of St. Francis, in the countyof Milwaukee and State of Wisconsin, have invented certain new anduseful -Improve-' ments in Cement Building; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in concrete buildingconstruc-v tion.

It is primarily the object of my invention to provide an .nnprovedconcrete building construction wherein the wall panels of the buildingmay be molded separately from the building andthen mounted in place,thus' greatly facilitating'the molding operation of said panels andpermitting a maximum thinness of the panels which is highly desirable inthe provision of a double wall Y structure to provide a dead air spacewithin the wall and thus provide an adequate heat insulation for thewall. It is more particularly my object to provide an arrangement forprocuring interlocking relation of the separately molded wall panelswith suitable wall columns which are cast in place.

A still further object resides in the provision of an arran ementwherein molded.

window and door ramesmay be embodied in the wall panel structure.

A still further object resides in the provision of a. roof structurecooperating with awall structure embodying the afore recited objects,and wherein the body of the a roof may be formed of separately moldedpanels similar to the wall panels. I

With he above and other objects and advantages in view, which will beapparent as the description proceeds, my invention I resides in thenovel features of construction,

combination and arrangement of the parts as hereinafter described anddefined by the,

ap ended claims.

n the accompanyingdrawings: Figure 1 is a horizontal sectional viewthrough the wall structure ofa building embodying my invention.

2 is a similar view showing a slightly Fi moded structure. 7

. Fig. 3 is a vertical sectional view through a roof and adjacent wallstructure embodying my invention.

Fig. 4: is a detail sectional view on the line 44 0f Fig. 3.

Referrlng now more particularly to the drawings, 5 designates each .of apair of concrete wall columns, which are preferably molded in place onthe foundation of the building, and 6 designates each of a plurality ofintermediate wall columns. Each of these columnsis provided in a pair ofsides with a pair of stepped inner shoulders and outer shoulders 7 and8, the shoulders of the corner panel 6 being formed in adj acent sidesof each column whereby to provide for an lar relation of the wall panelsassociated t erewith, while the shoulders of each intermediate columnare formed in opposite sides thereof- The inner and outer wall panels 9and 10 respectively are molded in flatsheets on'the ground in the mostsuitable manner. They are then applied to the walls, seating against thecorresponding shoulders of the columns, it being noted that the outerpanel 10 would in each instance be ing inner panel 9 by reason of thestepped relation 0 the seating shoulders 7 and. 8. In the structure ofFig. 1, the ends of the side edges of the outer panels are disposed atright angles to the planes of the panels, and the panels are heldagainst the shoulders 8 by the application of cement 11 to their edgeportions. The .edge faces of the a of slightly lesser width than itscorrespondpanels 9,-however, are beveled inwardly toward the inner sideof the panel and the inner side portions of the columns 6 are similarlybeveled. When the panels 9 are engaged a 'ainst the shoulders of thecorner column 5 t eir bevelededge faces are in mu- 1 'tual. engagement,and when the edge facesshown at 10 may be provided, having its edgeportions inwardly'ofl'set at 13 to en-' age the column shoulders 8, theouter face i of the panel thus lying flush with the outer faces of thecolumns. 7

When it is desired to provide a window in myimproved wall structure, Iprovide a ntense molded rectangular window frame It having its outerportions provided with stepped shoulders 15 similar to the shoulders ofthe wall columns, and the adjacent panels are properly shaped to fitbetween the members of this window frame and the adjacent columns, asshown in Fig. 1.

In Fig. 2, a slightly modified structure is shown wherein the side edgesof both the inner and outer panels are beveled to procure a positiveinterlocking relation with the correspondingly beveled column sides bythe insertion of key bodies 16 of cement between the side edge faces ofthe panels and the opposed face portions of the columns when the panelsare seated against the shoulders 7 and 8 of the columns. As shown inFig. 8, the upper ends of the wall columns are connected by roof sills17 having their bottom portions provided with stepped shoulders forseating the upper edges of the wall panels, said shoulders, as shownFig, 4 being adapted to also engage the stepped shoulders of the uppersill of the window frame 14 when it is desired to extend said windowframe to this height. Otherwise, relatively small panel sections may beprovide'dbetween the window frame and the roof sill, as will be obviousFor mounting roof panels 19 in proper inclined position, I provide anopposed pair of roof sills designated at 17 of considerably greaterheight than the other roof sills. The inner faces of the sills 17 a areformed with recesses extending in slightly inclined position from thetop of the sills 17 to a central point adjacent the top of the sills 17and the side edges of the roof panels are inserted in these recesses,the outer ends of the panels thus resting squarely on the lower sills17. A sealing body of cement 20 is disposed between the inner ends ofthe panels 19. These roof panels are molded on the ground similar to thewall panels 9 and 10 and are then set up in place, thus greatlyfacilitating the building of structures of this character. Reinforcemembers 21 extend longitudinally through the roof sill sections 17 andare downwardly bowed from the ends thereof, thus forming. tensionmembers of a truss structure and provide relatively great strength inthe roof in a most compact manner.

What is claimed is: n 3 1. In a concrete huildingconstructlon, a pair ofwall columns having inwardly facing stepped shoulders in their oppositesides,

bonding members connecting the columns pair of wall columns providedwith pairs of inwardly facing stepped shoulders in their opposite sides,a molded cemented frame between said columns and provided with inwardlyfacing stepped shoulders in its sides extending toward the shoulders inthe columns and pairs of wall panels disposed between the sides of theframes and the wall columns, and engaged against the inner faces of saidstepped shoulders of the frame sides and wall columns, whereby saidpanels are held by said shoulders in spaced relation against inwardmovement, and key bodies of cement disposed against the inner edge facesof the panels to hold the same against inward movement.

3. In a concrete building construction, a plurality of wall columns,pairs of opposed roof sills mounted on said wall columns, wall panelsengaged with said columns and roof sills, one pair of. roof sills beingof greater height thanthe other pair of roof sills and provided withgrooves in their inner sides inclined upwardly from the tops of saidother roof sills to the central upper portions of said higher roof sillsand roof panels having their side edge portions engaged in said groovesand having their outer edge portions seating on the lower roof sills.

In testimony that I claim the foregoing I have hereunto set my hand atSt. Francis, in the county of Milwaukee and' State of Wisconsin.

NICHOLAS FRISCHMANN.
